Maundy Thursday is the Thursday following Palm Sunday and is celebrated during Holy Week. It is part of the Triduum, or three holy days before Easter. It comes from the Latin mandatum novum, "new commandment," from Jn 13:34-35 (A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples). Maundy Thursday also commemorates the institution of the eucharist by Jesus "on the night he was betrayed."
